Pink Tourmaline, Diamond, White Gold Earrings, by Laura Munder

@davidmorrisjeweller Mozambique Paraiba Reef ring, set with 17.22ct Paraiba-like tourmalines and diamonds in white gold. Locked away beneath the harsh, dry scrubland of north-eastern Brazil was a Paraiba tourmaline of such extraordinary colour that, when it made its debut at the Tucson Gem Show in 1990, the tantalising ocean-like, green-blue gem sent buyers into a frenzy - driving up the price from hundreds to thousands of dollars per carat within days. The Paraiba tourmalines discovered in the Brazilian outpost of São José da Batalha, and two subsequent sites in neighbouring Rio Grande do Norte, were electric in colour, almost neon; a never-before-seen quirk of nature created by a high copper content.
